X, Y & Z represents 2, 12 & 17 relatively a. Write the electronic configuration of x, y, and z b. Place the elements in

olasank [31]

The electronic configuration of x, y, and z.

$x=1s^2$

$Y= 1s^22s^22p^63s^2$

$Z= 1s^22s^22p^63s^23p^5$

<h3>What is an electronic configuration?</h3>

Electronic configuration, also called electronic structure, is the arrangement of electrons in energy levels around an atomic nucleus.

$x=1s^2$

$Y= 1s^22s^22p^63s^2$

$Z= 1s^22s^22p^63s^23p^5$

x= Period 1 and group18

Y=Element is in period 3 and Group 2

Z=Element is in period 3 and group 17.

X, Y & Z represents Helium, magnesium, and chlorine.

The most appropriate word among the group of answer choices to fill in the blank is: a. Random sample surveys.

Sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

The various types of sampling used by researchers includes the following;

Systematic sampling.

Convenience sampling.

Stratified sampling.

Cluster sampling.

Random sampling.

A random sample survey is also referred to as a simple random sample (SRS) and it can be defined as a sampling technique that involves randomly selecting a subset of a larger population. Also, any result obtained through the use of a random sample survey can be generalized and applied to a larger population.

In conclusion, scientists and researchers prefer random sample surveys because their results can be generalized to a larger population.
